Cierium or Kierion (Ancient Greek: Κιέριον) was a town and polis (city-state) in the district of Thessaliotis in ancient Thessaly, which according to some ancient commentators, such as Stephanus of Byzantium was the successor to the Homeric Arne, the chief town of the Aeolian Boeotians in Thessaly, from which they emigrated to Boeotia.
